EDWARD M. MAN GOLD, 0F SEASIDE PARK, NEW JERSEY.

CISTERN-CLEANEB.

Application filed October 2, 1916.

To all whom it may concern:

Be it known that I, EDWARD M. MANGOLD, a citizen of the United States, residing at Seaside Park, in the county of Ocean, State of New Jersey, have invented certain new and useful Improvements in cistern-Cleaners; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in cistern cleaners of the type which comprise a container to be lowered into the cistern, after which the air in the container is released so that the sediment in the bottom of the cistern will fill the space in the container occupied thereby.

A novel feature of the invention is the provision of means for releasing the air valve and the entrance valve simultaneously.

The invention further resides in novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing in which Figure 1 is a side elevation of the device.

Fig. 2 is a vertical central sectional view.

Fig. 3 is a sectional view on line 33 of Fig. 2.

Fig. 4 is a sectional view on line H of Fig. 2.

eferring to the drawing 1 designates the cylinder, the bottom 2 of which is formed with an opening 3 normally closed by a flap valve 4:, formed from leather and suitably secured to the bottom 2. The valve & has fixed thereto a weight 5, which serves to positively hold the valve in a position to close the opening 3, said Weight provided with a ring 6, the purpose of which will appear later.

The top 7 of the cylinder is provided with a tapered valve seat 8 which is adapted to receive the tapered valve or plug 9, said plug having its upper and lower ends pro vided with eyes 10 and 11. The cord 12 has its upper end connected to the eye 11 and its lower end connected to the ring 6, thereby flexibly connecting the plug 9 and valve 4.

The cylinder 1 is provided with a yoke 13, said yoke being provided with a socket 14: for receiving the lower end of the handle Specification of Letters Patent.

Serial No. 123,365.

15, said handle serving as means for lowering the cylinder into the cistern.

To the eye 10 is secured the lower end of the cord 16, which may be of any desired length so that the valve 9 can be unseated and the valve 4. lifted.

In operation the cylinder is lowered into the cistern, and at which time the valves 9 and t are closed, but as soon as the cylinder reaches the bottom of the cistern the cord 16 is pulled upwardly to remove the valve 9 from its seat, and since said valve is connected to the valve e by the cord 12, the latter valve, which has up to this time been closed against the water pressure below the cylinder, will also be lifted from its seat. The mud and sediment at the bottom of the cistern will now rush into the cylinder through the opening 3 and displace the air which escapes through the opening 8 in the top of the cylinder. After the sediment has filled the cylinder the valve 4: will automatically close under the action of the weight 5 to prevent the sediment from passing from the cylinder as the latter is lifted from the cistern.

To the under surface of the bottom 2 is secured a V collecting flange 17 which serves to direct the sediment to the opening 3 when the cylinder is moved across the bottom of the cistern.

What is claimed is A device for cleaning cisterns, comprising a cylinder, the bottom of said cylinder having an opening formed therein, a flap valve secured to the bottom of the cylinder to open inwardly, a weight mounted on the valve, a valve seat formed in the head of the cylinder, a valve engageable with the seat, a cord connecting the flap valve and the last mentioned valve, a second cord secured to the upper end of the last mentioned valve and serving when pulled to unseat both of said valves, and a V-shaped collector flange secured around said opening in the bottom of the cylinder and having its legs extending to the margin of the cylinder bottom.

In testimony whereof, I aflix my signature, in the presence of two witnesses.

EDWARD M. MANGOLD.
